Abstract

A dipped activated carbon for preventing acidic toxic gas is prepared through proportionally mixing the solution of copper ammonium carbonate with carbonate of alkali metal, silver nitrate and ammonia water to obtain a liquid mixture, dipping activated carbon in it, and drying.

Description

technical field [0001] The invention relates to an activated carbon and a production method thereof, in particular to an acid poisonous gas impregnated activated carbon and a production method thereof. Background technique [0002] At present, the impregnated activated carbon used to prevent acid and poisonous gas is made of activated carbon with active components, and the active component (impregnated liquid) is an inorganic alkali; the production method is: make a solution of the inorganic alkali, impregnate it on the activated carbon and then Dry it. Although this impregnated activated carbon can adsorb acidic poisonous gas, it has the disadvantages of narrow application range and poor use effect. Contents of the invention [0003] In order to solve the technical difficulties of the existing impregnated activated carbon such as narrow application range and poor use effect, the invention provides an acidic and poisonous gas impregnated activated carbon and a production ...
